APPENDIX B CAUTIONS ON DESIGNING TARGET SYSTEM

Figures B-1 and B-2 show the conditions when connecting the emulation probe to the conversion connector.

Follow the configuration below and consider the shape of parts to be mounted on the target system when designing a

system.

In the product names described in this appendix, SWEX-120SE-1, NQPACK120SE, YQPACK120SE, and YQ-

GUIDE are products of TOKYO ELETECH CORPORATION.
